Samson Airline Series Wireless Handheld Mic System with AX1 Plug-in Handheld Transmitter, AR1 Receiver (Channel U1/801.375 MHz) , Q7 Mic and Power Supply

AirLine Handheld - XLR Microphone System
The super-compact Ax1 Handheld Transmitter lets you convert any dynamic microphone into a wireless mic. Just plug in the Ax1 and you're good to go! And,because it's a little smaller than an XLR connector, you won't even know it's there.

Like all AirLine transmitters, the Ax1 operates on a triple-A battery with 14-hour battery life and delivers reliable reception and transparent sound over long ranges. Plus UHF (Ultra High Frequency) means clearer frequencies withless interference. Once you fly with AirLine, no other wireless makes sense.
